Caribbean monk seal

The Caribbean monk seal (Neomonachus tropicalis), also known as the West Indian seal or sea wolf, is an extinct species of seal native to the Caribbean. The main natural predators of Caribbean monk seals were large sharks, such as great whites and tiger sharks, and possibly transient orcas (though killer whales are not often sighted in the Caribbean); however, humans would become their most lethal enemy. Overhunting of the monk seals for oil and meat, as well as overfishing of their natural prey, are the likely reasons for the seals' extinction.
